from a point considerably below the junction with the jambs, which gives it a broken appearance. An inner moulding, finished with well wrought bases, runs round the exterior of the windows. The roof of this church, like that of so many erected at a somewhat later period, is covered with overlapping stone slabs, which rest on a pointed barrel vault (Fig. 927), for the purpose of supporting it. This is the earliest example we have met with of this form of vault, which became very common in the churches of the following period. That at Lincluden, already referred to, is similar, but had a groined vault beneath it. The vault is ornamented with moulded ribs at intervals, springing from small moulded corbels. There is also a ridge rib, and bosses occur at the junction with the curved side ribs. The buttresses are simple in outline, and have a deep series of set offs at top, and those next the doorway have small cusped niches in the face of each. The stone work of the roof is very carefully executed, every stone being curved so as to throw the water away from the joints. The cornice is rather more prominent than usual. [Illustration: FIG. 929.--St. Bride’s Collegiate Church. Sedilia.] [Illustration: FIG. 930.--St. Bride’s Collegiate Church. Tombstone, with Shield and Douglas Arms.] The entrance to the sacristy is by an unusually handsome doorway (Fig. 928), having two orders of shafts and mouldings. The carving of the caps has been very fine, but is sadly damaged. In the sacristy there are a piscina and a locker, and in the south wall of the choir the remains of a triple beautifully carved sedilia (Fig. 929) and a piscina. The sacristy is roofed with overlapping stone flags, supported on a vault. Some elaborate monuments have been erected in the church (see Fig. 927) in memory of the two Archibald Douglases, Earls of Forfar, one of whom was mortally wounded at Sheriffmuir (1715). Some ancient carved stones are also preserved at the east end, one of them being a tombstone containing a shield, with the original three stars of the Douglas arms (Fig. 930). ST. DUTHUS’ CHURCH, TAIN, ROSS-SHIRE. [Illustration: FIG. 931.--Old St. Duthus’ Church. Plan.]
